DISH- WASHING MACHINE.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed July 24, 1918. Serial No. 246,524.

To all whom it may concern l 3e it known that I, ToM WILLIAMS, a citizenof the United States, residing Pilot, in the county of Fremont and Stateof Wyoming, have invented certain new and useful Improvements inDish-Washing Matchines, of which the following is a specificaion. Thisinvention relates to a dish wash- 1ng machine and has for its object toprovide a device of this character which shall be of simpleconstruction, contain few parts, and which will force the water withinthe receptacle over the dishes contained therein and wash themthoroughly.

A further object of the invention is to provlde a dish washing machinewith a receptacle for the dishes and the water for washing the same withan inclined bottom 4 which Wlll cause the water to gravitate to one sideof the receptacle and mounttherein to be covered by the water a pair ofpump cylinders, the pistons of which are operated by a handle on theoutside of the receptacle whereby the water is drawn into the cylindersthrough perforations in the walls thereforced outwardly and upwardly thesame perforations to be disover the dishes within the recepof andthrough tributed tacle.

With these objects in view, together with others which will appear asthe description proceeds, the invention resides in the novel formation,combination and arrangement of parts, all as will be described morefully hereinafter, particularly pointed out in the claims, andillustrated in the accompanying drawings, in which Figure 1' is a sideelevation of the improved dish washing machine, a portion being shown insection.

Fig. 2 is an end elevation of the dish washing machine and,

Fig. 3 is a detail perspectlve view of one end of one of the pumpcylinders.

In the drawings, 10 indicates a receptacle for dishes, here shown asmade of box-like form with an open top fitted with a cover 11 and havingan inclined bottom 12 that extends from one side of the receptacle tothe other with an upward inclination as shown in Fig. 2, the lower oracute angle formed by the bottom and one side at 13 restlng d1- rectlyupon the support for the washlng machine, the opposite slde beingsustalned by legs 14 fastened to the ends of the receptacle 10. Withinthe receptacle and extending cross wise of the same at the center of itslength is a stand 15 which serves to divide the receptacle into .twoparts and also serves as a support for the dishes when placed in themachine to be washed.

Within the receptacle at the lower or acute angle 13'are mounted twopump cylinders 16, said cylinders, being each pivoted at one end to theend of the receptacle-so as to swing vertically. The opposite end ofeach cylinder is fitted with a removable head 17 through which passes apiston rod 18 on the inner end of which is a piston 19.

' Through the top of each cylinder 16, at each end, is formed a hole 21through which water passes into the cylinder when the piston is movingto the opposite end and out of which it is forced when the piston movestoward the perforation. The piston rods v18 of the two pumps arepivotally conne ted to the lower end of a swinging arm 20 hinged at 22to the side of the casing 10 near the top thereof and extending throughthe casing is connected to a handle 23 that projects above the top ofthe washing machine in position to be grasped by the hand for thepurposeof swinging the arm and operating the pumps.

Above each end of each cylinder 16 is a bracket 24, each bracket beingfastened to the front wall of the casing 10 within the same and hasadeflector 25 hinged thereto, these defle tors being hinged in suchmanner and position that when elevated as shown in Figs. 1 and 3, theopenings 21 in the pump cylinders will be uncovered. but when turneddownwardlv into horizontal position the defiectors will overlie theopenings and preventthe stream of water from the pump passing over thedishes. To operate these defle tors there are provided rods 26 conneting all of said deflectors and an operating extension 27 passes througha perforation in the end of the casing 10 and terminates in a ring 28 tobegrasped by the fingers, whi h when pulled, will turn the deflectorsinto horizontal position as is evident.

In using this dish washing machine, the dishes to be washed are stackedwithin the casing 10 on each side of the stand 15 and around the same.Hot water is then poured into the receptacle until it covers the pumpcvlinder. Due to the inclination of the bottom 12 of the receptacle, thewater will all Mill run toward the lowest corner where the pumpcylinders are situated and will maintain 'them submerged. The cover 11will now be closed over the receptacle and upon manipulating the handle23 by rockin it to and fro the pistons 19 will be moved from end to endof the pump cylinders and alternately draw the water into the cylindersand force it outward through the openings 21 in streams which will riseupwardly to the top of the receptacle and then fall downwardly upon thedishes. This operation being kept up for a suitable length of time,these streams of water will serve to thoroughly cleanse the disheswithout the necessity of rubbing or handling them in any manner. Whenthe water in the receptacle is to be removed it will only be necessaryto withdraw the plug 30 from the outlet 31 in one side of the reeptacle.a

The foregoing description andthe drawings have reference to Whatmay be,considered the preferred, or approved form of my invention. It is to beunderstood that I may make such changes in construction and arrangementand combination of parts, materials, dimensions, et cetera, as may proveexpedient and fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desireto secureby Letters Patent, is

1. A dish washing machine comprising a receptacle having an inclinedbottom, a pair of pump cylinders within the receptacle at the lowestpart thereof, said pump cylinders being each pivoted at one end to the Ia swinging arm hinged to receptacle and each having an opening throughthe top side thereof at each end, a piston within each of said pumpcylinders, the side of the receptacle and pivotally connected to thepump pistons for operating the same, a handle without the. re:eptacleconnected to said swinging arm for imparting motion thereto, and adeflector adapted to be swung over each of said perforations in thecylinder to interrupt the flow of water to the dishes.

2. A dish washin machine comprising a receptacle, a pair 0 pumpcylinders within said receptacle, each pivotally connected at one end tothe receptacle, said cylinders each having an opening through the top ateach end for the inflow and outflow of water, a piston within each ofsaid cylinders, a swinging arm ceptacle and pivotally connected to thetwo pump pistons, a handle withoutthe receptacle connected tov saidswinging arm for operating the latter, a bracket secured within thereceptacle above each end of each of said pump cylinders, a deflectorpivoted to each of said brackets and adapted to swing over an opening ina pump cylinder, connecting means between all of said deflectors foroperating them in unison, and a rod extending through the end of thereceptacle for operating the deflectors.

In testimony whereof I afiix my signature in presence of two witnesses.
